LASER stands for "Light Amplification by Stimulated Emission of Radiation." It is a technology that produces a coherent beam of light through the process of stimulated emission, where photons are emitted from excited atoms or molecules when they return to a lower energy state. This process amplifies light, resulting in a highly focused and intense beam that can be used in various applications, from medical procedures to communication technologies. The unique properties of laser light, such as its coherence and monochromaticity, make it valuable in numerous fields.

Who discovered laser?
Lasers were not discovered, but rather were invented - by a man called Theodore Maiman. Maiman created the first Laser, a ruby Laser, in 1960."L.A.S.E.R." is an acronym standing for:LightAmplification byStimulatedEmission ofRadiation (Not nuclear radiation, but light or photon radiation)
Who invened lasers?
Well the principle of stimulated emission was discovered by Albert Einstein. But first laser was fabricated by Theodore Mainman
When was the first laser tag created?
The first laser tag, originally known as "Photon," was created in 1984 by George Carter III. This innovative game combined elements of tag with laser technology, allowing players to engage in competitive gameplay using infrared-emitting devices. The concept quickly gained popularity, leading to the establishment of various laser tag arenas and franchises around the world.
What is the list of weapons that start with laser?
The list of weapons that start with laser are: Laser axe Laser bow Laser chaingun Laser chainsaw Laser cannon Laser crossbow Laser daggers Laser gatling gun Laser knife Laser machete Laser machine gun Laser rapier Laser rocket launcher Laser scythe Laser shotgun Laser slingshot Laser sword Laser tommy gun Laser whip and countless others
When was the first laser built?
The first working laser was built in 1960 by Theodore H. Maiman at Hughes Research Laboratories. It was based on the concept of a maser (microwave amplification by stimulated emission of radiation) with the wavelengths of light shrunk to the optical range.
How did lasers come to be?
The concept of a laser was first proposed by physicist Arthur Schawlow and engineer Charles Townes in 1958. They built on the theoretical work of physicist Max Planck and Albert Einstein. The first working laser was developed by Theodore Maiman at Hughes Research Laboratories in 1960.
What range does a lastec concept DVD system lt1 20.20 speedscope have?
The Lastec Concept DVD System is a combination of the Laser speed gun and a DVD recording system. The range of the individaul model of the LI 20-20 laser gun remains the same whether or not it has a Concept system attached to it. The LTI 20-20 Utralyte 100 has a range between 23 to 610 metres. The LTI 20-20 Utralyte 1000 has a range between 20 to 1000 metres. The Manufacturer's web site explains all.
What is hotter lava or laser?
laser
Which laser type is used in laser printers?
The old laser printers used He-Ne laser , and the modern laser printers use infrared laser .
Are laser pointers as bad as laser pens?
Laser pointers and laser pens are basically the same thing. A laser pen is a laser pointer with a pen attached.
How is a facsimile reproduced by a laser printer?
using the concept of static electricity, which allows electricity to stick to a device inside the printer called the drum, which in turn creates electrostatic images
